Wang Zhihuan was clever since he was a child, but his writing was weak. Generosity has a general idea, and it is very attractive and talented. He entered the official position with the shadow of the door, granted Hengshui the master book, and married the third daughter of Li Di, the county magistrate of Hengshui. Later, he was slandered and dismissed from office. In the first year of Tianbao (742), Wen 'an county commandant was recruited, and his life was innocent and his management was fair. He died in Wen 'an Post at the age of 55. Buried in the ancestral grave of Beimang Mountain in Luoyang County.
Wang Zhihuan didn't preach in Old Tang Shu and New Tang Shu, and the biography of talents in Tang Dynasty was also very simple, saying that Wang Zhihuan was a great master. Jin Neng, a native of Tang Dynasty, wrote a preface in the Epitaph of Wang Fujun, Taiyuan, Wen 'an County, Tang Dynasty, which recorded that Wang Zhihuan's Jinyang moved to Jiangxi County, Jinyang (now Taiyuan, Shanxi Province) was his native place, and his ancestors moved to Jiangzhou (now Xinjiang, Shanxi Province) when he became an official.
According to the epitaph, Wang Zhihuan was born in Wu Zetian's hanging arch for four years (688), four brothers, and his career ended. At that time, the royal family in Taiyuan was a noble family. Wang Long, the fifth ancestor of Wang Zhihuan, was the secretariat of Jiangzhou after Wei Dynasty, which may be the reason why he moved to Jiangzhou. Great-great-grandfather Wang xin, a doctor and writer in the Sui Dynasty, became an Anyi county magistrate in the Tang Dynasty.
